How to monitor GPU memory usage on px2

Autonomous Vehicles DRIVE PX 2 General
1

Hi,

I am running driveworks samples with drive px2.
I want to monitor how much GPU memory is being used while running multiple samples.

I checked it using tegrastats, but GR3D_FREQ and GR3D_PCI always get 0%. I also know that tegrastats does not show the memory usage of the GPU. (Nsight system tool is the same)

Running nvidia-smi I see GPU memory usage.

Is there any way to check GPU memory usage on Drive px2?

Dear @Jaeeun_Kim,
Unfortunately there is no nvidia-smi type command for DRIVE platform. tegrastats can measure only iGPU usage details.

I See.
So, can’t I check the gpu memory usage on the drive platform at all?

Even if I use tegrastats, iGPU, dGPU usage keeps getting 0%.
I saw in another forum article that updating this issue, is there any updated tegrastats for drive px2?

Dear @Jaeeun_Kim,
Unfortunately there is no releases targeted for DRIVE PX2. We have fixed the issues with tegrastats on DRIVE AGX. Please consider upgrading to DRIVE AGX if possible.
